COMBINED MATCH SAFE AND IGNITING- DEVICE.

Specification of Letters Intent.

Patented Mar. 30, 1920.

Application filed August 22, 1918. "Serial No. 250,945.

This invention relates to combined match safes and igniting devices ofthe class illustrated in my co-pending applications Nos. 21%,592 and220,159, in which an igniting strip is wound around a drum, the supplyof matches standing up withinthe coil. In

said application 214,592, the igniting strip a is in the form of a coilconfined within the drum, the end of the strip being led out through anaperture in the drum wall, and wound around the drum; an annular capserving to confine the coil within the drum.

The objects of the present invention are to simplify and improve thestructure, to

reduce the cost of'manufacture, and to facilitate assembling anddisassembling the device, with provision for firmly securing the partstogether. One of the aims is to provide for assembling and disassemblingwithout the use of tools, and by a simple operation that can be easilyunderstood and practised.

In carrying out my present improvements, the coil-containing drum issupported by means of a pedestal upon a base, the drum and pedestalbeing preferably spun from a piece of sheet-metal and forming a singleshell. diameter than the drum, and an exterior flange at the top of thepedestal may constitute the floor of the drum. The strip forms anannular coil to lie in the drum and rest upon its floor. Through anopening in the wall of the drum, the end of the coil may be drawn out towrap around the drum.

In order to,complete the device, there re main to be mentioned a cap toconfine the coil within the drum, a box to serve as a match-safe, andmeans for securing the pedestal upon the base. These three require mentsmay, according to my invention, be supplied by means of a single device,which may be spun or drawn in one piece from sheet-metal, and maycom-prise for its main portion a cylindrical box or shell constitutingthe match-safe, said box having at its top a flange which serves as anannular cap to retain the coil within the drum. Said The pedestal mayhave less i'natch-safe or box is confined within the coil, and it has atits bottom a set of exterior rolled threads which screw into a socketprovided upon the base. The flange at the top of the matchbox bears downupon the top edge of the drum shell, so that, by revolving the cap, thelatter is drawn down tightly upon the drum shell, thereby fastening itto the base. The diameter of the pedestal is ample, so that a solid,substantial structure is produced. The socket in the base is preferablyconstructed or spun from SllQGt-lllGtfll, rolled with threads which fitthe threads in the match-box. The pedestal fits over said socketconcealing the threads.

These three principal parts, the base, the

drum with its pedestal, and the match-box with its cap and threads, maybe each formed inexpensively from sheetanetal, and yet taken togetherthey form a solid structure not liable to looseness or other weakness.

Other features and advantages will here inafter appear.

In the accompanying drawings,

Figure 1 is an elevation of a combined match-safe and igniting device,embodying my improvements in one form.

Fig. 2 shows the same in vertical section; the section being takenthrough the clip which secures the outer winding of ignition coil.

Fig. 2* is a modification to illustrate the socket made separately andattached to a base of glass or other material.

Fig. 3 shows the three main parts of the device assembled in elevation.

Fig. 4.- is a perspective view of one of the shells seen at Fig. 3,viz., the drum which contains the coil of ignition strip, and thepedestal which said drun'i surmounts.

An annular coil 10 of igniting strip, usually wound upon a hollow core11, is placed in a drum 12 and rests upon the floor 13 thereof. The drumrises from a hollow pedestal 14:. The pedestal, floor and drum may bedrawn or spun up from a single piece of metal, said floor 13 being inthe nature of an exterior stiffening flange at the top of the pedestal,the latter being of less diame* ter thanthe drum, but still of amplesize to secure a firm footing upon the base, which is illustrated in theform of a dished member 15.

The coil 10 is led out through an opening 16 in the side wall. of thedrum, and a layer 17 thereof is wrapped around the drum,

socket 23, which may be the center of the base 15.

drum and pedestal firmly thereon. This attachment is efiected preferablyby means of threads 21 rolled upon the lower portion of the box, toengage threads 22 rolled in a struck up from This connecting shell is ofrelatively large diameter, and its threaded connection enables it to beforced securely down upon the base without liability of becomingloosened from rough usage. It will be seen that the shell 20 may beintegral with the cap 18 and may have an integral floor 2% upon whichthe matches may stand, so that a substantial economy is effected inmaking the parts and assembling the device. The

cap 18 serves as a stiffening brim for the match box 20.

The coil 10 may be placed in the drum, and the outer winding 17 thereofmay be introduced edgewise down through a slit 25 into the large opening16 in the side of the drum, and this winding may be pulled out farenough to wrap once around the drum, the leading end 26 thereofoverlapping a portion of the winding. This overlapping portion 26 maybe'clamped to the underlying strip portion, and both windings may beclamped against the drum, thereby se curing the winding against slippingaround the drum at the match-striking operation.

In assembling, the drum and pedestal shell may be stood upon the base15, and then the cap and matclrbox connectingshell may be insertedwithin the drum and coil 10, and passed down through the pedestal 1 1,until the threads 21 upon the bottom of the box engage the threads 22upon the socket, whereupon, by turning the cap, the connecting shell maybe rotated to draw the cap down uponthe drum and force the pedestal 14toits seat upon the base; said pedestal preferably fitting closelyaround the socket 23 to prevent sidewise displacement.

The clip for the outer end 26 of the ignition strip may be in the formof a bent wire having a middle portion 27 serving as a pintle which ishinged in a bearing 28 punched up and formed from the body of the drum.The clip further comprises sides 29 which extend down from said pintle.At their lower ends the sides bend toward each other to serve as a pivotfor a roll 30 which is adapted to catch under the edge of an outwardlyprojecting flange 31 formed at the junction of the sldes and bottom ofthe drum to confine the strip against downward displacement; said rollspringing under the edge of the flange, which is dished upwardly, Fig.2, so that the roll will snap into its locking position from which itcannot be moved except by the application of considerable force, so thatthe clip is not liable to be accidentally swung out to re lease thestrip. As the roll is sprung under the edge of the drum, the sides 29 ofthe clip are brought firmly into contact with the strip, said sidesbeing bowed inwardly or formed to press the overlapping portions of thestrip together and to press them against the drum. The device forms aspringy means tending normally to draw the clip against the strip.

A downwardly projecting rim 32 upon the cap 18 fits over the thin topedge of the drum to protect it and to cover up the slit- 25 in the topthereof, as well as to confine the strip against upward displacement.

At Fig. 2 the base 33 is made of glass, wood or other material, and thesocket 23 may be formed with a bottom 34. to be attached to the base byrivets 35.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
